The SQ80 features 3 digital wavetable oscillators for each of its 8 voices which are fed through analog 4-pole lowpass filters (-24dB gain) with resonance. Sound parameters can be modulated by 4 envelopes, 3 LFOs and several MIDI sources. The SQ80 also has a predecessor, the ESQ1, which can do most of the same stuff.

Although the technology may seem obsolete, these synths can produce a wide variety of interesting and extremely usable sounds. Thanks to the lo-fi oscillators and the analog components it can sound very digital and dirty, but also very analog and warm. Which is a good thing because modern synths often tend to sound rather clean. Now you can experience this great classic synth with the SQ8L!

The SQ8L ("L" stands for "Light"), there are only a few limitations. Those are:

• Polyphony limited to 8 voices
• Program change messages ignored
• When used with a sequencer, the only sound the host can save within the song file is the one in the edit buffer
• No Split/Layer to combine several sounds
• No internal sequencer
• No automation (only MIDI input)
